Abstract

High temperature tensile properties of Inconel 713C without and with Yttrium microaddition have been investigated. Yttrium addition affected the solidification structure with promotion of equiaxed grain formation in the center of mold. Ultimate tensile strength increased from approximately 892 to 1006 MPa while the elongation increased from approximately 13% to 21% by 0.05 mass% Yttrium addition. 0.05 mass% Yttrium addition in Inconel 713C alloy showed optimum high temperature tensile property.
